PAPER-BOX-SETTlNG-UP MACHINE.

SPECIFICATION forming part of Letters Patent No. 515,207, dated February 20, 1894.

Application filed May 2,1893. Serial No. 472,680- Nomode1- To all whom it may concern.-

Be it known that I, GEORGE W. GLAZIER, a citizen of the United States, and a resident of Salem, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in-Paper-Box-Setting-Up Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements on the patent granted to me July 21, 1891, No. 456,485, for paper box setting up machines, and it is carried out as follows, reference being had to the accompanying drawings, wherein Figure 1 represents a top plan view of the improved machine. Fig. 2 represents a front elevation of the same. Fig. 3 represents a vertical section on the line 33 shown in Fig. 2. Fig.4 represents a similar vertical section of the head of the machine. Fig. 5 represents a vertical section on the line 55 shown in Fig.4. Fig. 6 represents a detail plan view of the box supporting plate. Fig. 7 represents a cross-section on the line 7-7 shown in Fig. 6. Fig. 8 represents a detail top plan view of the picker plate or blank feeder. Fig. 9 represents a bottom plan view of the same. Fig. 10 represents a section on the line 10-10 shown in'Fig. 9. Fig. 11 represents a section on the line 1111 shown in Fig. 9. Fig. 12 represents a cross-section on the line 1212 shown in Fig. 9. Fig. 13 represents a detail perspective view of the yielding friction shoe for holding the end blank against the blank supports on the picker plate during the pasting operation. Fig. 14 represents a cross-section of the same on the line l414 shown in Fig. 13; and Fig. 15 reprepresents a perspective view of the paste board box that is being put together by the improved machine.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

A, A, represent the upright frames or standards in the lower portions of which is journaled in bearings, the rotary driving shaft B which is set in a rotary motion by belt power applied to the pulley B which is loose on said shaft and is adapted to be frictionally connected to a suitable friction clutch, at-

tached to said shaft, by the depression of a Patent.

B is a spring for automatically raising said treadle lever when the operator releases his foot pressure thereon as usual.

On the driving shaft B is secured a pinion b, the teeth of which mesh in the teeth of a spur gear 0 on the cam shaft 0, as shown in Figs. 1 and 2.

In suitable ways on the frames A, A, is guided the vertically movable post or horn D on the upper end of which is located a base block E provided with laterally adjustable box supports E, E, which are adj ustable sidewise according to the width of the box that is being set up as shown and described in my former patent. The post or horn is caused to move upward by means of a cam F secured to the shaft 0 which cam has a semi-circular, concentric andnon-operative surface f shown in Fig. 3 for the purpose of holding the post or horn D stationary when it is in its lowest position to permit the removal of the finished box and replacing it with another one to be pressed; by the use of a cam as the actuating mechanism for raising the said post or horn, proper and increased time is givenfor the operator to remove and replace the boxes and the capacity of work is greatlyincreased thereby as the machine may be run at a greater speed than those in which a crank is used for this purpose on account of the comparative longer rest which may be given to the horn or post for the removal and replacing of the boxes.

The connecting mechanism between said cam F and the vertically movable horn D is constructed as follows:

G and G is a pair of toggle joint levers pivoted together as shown in Fig. 3; the upper end of the lever G is pivoted to the lower end of the post or horn D, and the lower end of the lever G is pivoted to a stationary, or slightly yielding block or cross bar G; to one of the said toggle levers, preferably to the lower one is connected a link G having a roll g jourpaled at its rear end and adapted to bear against the cam F for the purposeof guiding said link I prefer to pivot to it at or near its rear end, a rock lever G the lower end of which is pivoted at g to the frame of the machine or other stationary part. The weight of said post or horn D causes it to descend when the cam F releases it thus causing the roller 9 on the link G to be held at all times in contact with said cam F.

In this my improved machine, I make use of a separate and independent cam mechanism, for actuating the pasting device and another cam mechanism for operating the feeding of the end blanks from the pile to the pressing device by which arrangement the machine can be properly timed and adjusted so as to allow the pasting fingers to get out of the way of the picker slide without interfering with the latter during the feeding of the pasted end blank and also to prevent the too sudden dropping of the pasting fingers into the paste, thus preventing the splashing or sputtering of the paste onto the end blanks and portions of the machine.

The end blank feeding mechanism is similar to that shown in my previous patent and consists of a rock-lever I-I pivoted in its lower end on the shaft B and actuated in one direction (toward the rear) by means of a cam H acting on a pin or pin and roll it on said lever H, and in the other direction (toward the front) by the influence of a spring H, attached in one end to the lever H and in the other to the lower end of the post or horn D, or to the frames A, A, or to any other convenient part of the machine as may be desired. To the upper end of the lever H is adjustably connected a rod 1' the forward end of which is pivoted to the rear end of the picker slide I which is longitudinally movable in suitableguides as usual in the head of the machine below the pile of end blanks K arranged between the adjustable inclosing walls L, L, L, having at the front thereof, a vertically adjustable gate Zv terminating in its lower end as a horizontal plate Z in a manner and for the purpose as shown and described in my above mentioned patent. To the forward end of the picker slide I is secured a pair of rigid end blank supports 1, I, which are longitudinally adjustable relative to the forward end of said picker slide preferably by means of set screws '11, d, as shown in detail in Figs. 8, 9, 10, 11 and 12. The object of such longitudinal adjustment of the said end blank supports is to compensate for various sizes of end blanks used for boxes of varying sizes.

To the under side of the picker slideI is adjustably secured a picker 1, the forward end of which is adapted to be adjusted with a great degree of nicety above the forward end of the picker slide I so as to set it relative to the latter in proper position according to the thickness of the end blank K that is being used for making the boxes; said picker is preferably secured in its rear end to the under side of the picker slide I and provided near its forward end with an adjusting screw 1' as shown in Figs. 9 and 10.

To the frame of the machine is secured an arm orprojection A provided with an ad justable stop screw a (Figs. 3 and 4) against which the picker carrying lever H is brought to a stop when at the limit of its forward stroke by which arrangement the forward motion of said lever, caused by the spring H, may be limited and adjusted very carefully in accordance with the amount of feed desired to be given to the pasted end blank so as to leave it in a proper position to be stuck on the box body by the pressing de: vice. By the'arrangement of such adjustable stop device a the lever H will always be brought to a stop at the desired time for the purpose stated independent of any wear that may take place on the camll or the pin or pin and roll h on the lever H.

M is the paste receptacle in which are arranged the notched spotter bars N, N, and N which are raised and lowered in the paste receptacle M so as to transfer a portion of the paste in spots to the under side of the lowest end blank'K in the pile in a manneras fully shown and described in my above mentioned patent. Each spotter bar N is suspended as usual from pivoted links it, n, one of which has an upwardly extended arm or lever 71. as usual which is connected by means ofa link 0 to a lever 0 attached to a rock shaft 0" having secured to it a lever O to which is pivoted a rod Q whichis adjustably connected to a rod 0 (preferably by means of a right and left handed screw coupling 0 shown in Fig. 3) the lower end of which'rod is pivoted to a l'everP hung at p to the frame A and provided with a pin or pin and rollp actuated by a grooved cam P secured to the rotary shaft 0 as shown in Figs. 1 and 3.

The transverse spotter bar N is for the purpose of applying paste in spots to the under side of the blank at or near its forward edge. This bar N is supported by arms 07. that are pivoted at n and the bar is slotted for passage of projections or extensions n on the side bars N. N. by which an up and down rocking movement is imparted to the said i transverse bar during the forward and backward'swing of the side bars.

In practice I prefer to attach a spring 0 to the rod 0 and to the upper end of the frame A or its connections for the purpose of balancing the lever P and its connections to the rock shaft 0.

By means of the adjustable coupling 0 the dip of the pasting or spotter bars may be controlled and by accurately setting the cams H and P. the proper motion of the pasting bars can be adjusted and timed to a nicety relative to the end blank feeding mechanism.

From the above it will be seen that in this ism is operated independently ofthe end blank-feeding mechanism for the purpose as herein above fully set forth.

The supporting block E is longitudinally adjustable on the upper end of the horn or post D by means of a regulating screw E screwed into the front portion ofsaid horn or post and preferably provided with a collar E guided in'a recess 6 on the under side of the said block E as shown in Figs. 3, 4 and 7. By this arrangement the position of the box supporting block relative to the forward position of the end blank as it is ready to be stuck on the box body can readily be adjusted by the operator from the front of the machine, and a nice adjustment of the connection between the upper end of the feed lever H and the picker rod 2' is therefore not essential.

R is'the stationary head of the machine located above the box supporting block E and secured to the standards S, S, of the machine or other stationary part as shown in Figs. '1, 2, 3, and 4. Adjustment of the headRis not necessary as the slight adjustment given to the box supporting block E is only intended to compensate for any variation in the thickness of the cardboard composing the box body so as .to bring the edge of the box bottom into proper-relation to theforward edge of the end blank that is to close the end of the box. On the under side of said head R is acavity or recess R containingan upwardly yielding shoe T, preferably made with longitudinal downwardly projecting lips t, t, on its sides as shown in detail in Figs. 13 and 14:, the said lips t, t, beingupwardly inclined at their rear portion as shown in said Figs. 13 and 14 as well as in Figs. 3 and 4. The end blank K after being pasted and while resting on the rigid blank supports I, I, is held with a proper friction against the latter by the spring pressed shoe T until it is stuck onto the turned over edges is, it, of the box body K during the upward motion of the post or horn D and its box supporting block E on which said box body is held during the setting up operation as shown in Fig. 4:. After the end blank has been pressed onto the edges of the box body by the pressure of the box supporting block E against the under side of the head R, the blank supports 1, I, are automatically withdrawn allowing the boxto be removed after the post or horn has commenced to move away from the upper stationary head R.-

The shoe T is preferably provided with stem or spindle T passing loosely through a vertical perforation in the head It, and a spring T arranged on said spindle between said shoe and the under side of the head R as shown in Figs. 3, 4, 13 and 14:.

t, t, are nuts or equivalent devices secured to the upper end of the spindle T to prevent the shoe T from being forced out of the cav- 5 ity in said head R as shown in Figs. 3 and at.

By the arrangement of the rigid blank supporting arms I, I, on the picker slide and a yielding shoe overhead the blank while being fed, is caused to move in a straight path without danger of being twisted and is also held more firmly in position during the setting up operation.

In the operation of the machine the boxbody K" is placed with its turned overedges k, in, resting on the box supporting block E while the latter is away from the stationary head R; by the pasting device the lowest blank K- in the pile is pasted on its under side in spots or otherwise and fed by the picker slide to the position shown in Fig. 4: where it is held between the picker bars I, I, and the side lips of the yielding shoe T, and the blank is set up against the turned over edges of the box body when the box supporting block is with its box thereon forced against the under side of the pasted blank and the head after which the post or horn descends to per mit the reversal, removal and replacement of another box, while the picker slide moves backward and then forward for pasting and feeding another end blank and so on during the operation of the machine.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claim 1.
